A new research in the National Institute of Standards and Technology (NIST) and the university of Pennsylvania is working towards a Graphene based structure that can be promising for capturing hydrogen. Graphene is not really suited to store hydrogen, but if you stack oxidized Graphene sheets (in a Graphene-Oxide-Framework, or GOF) than it can hold hydrogen in higher quantities. The team says that GOFs can store at least a hundred times more hydrogen than ordinary Graphene Oxide. This can potentially be very useful for fuel-cells or other applications.
